R-Patz and Katy Perry are spotted together at wedding rehearsal... as it's claimed their friendship caused Kristen Stewart split

First there was their big night out in New York and now Robert Pattinson and Katy Perry have been spotted watching a wedding rehearsal in Santa
Barbara together.

The Twilight Saga hunk and the Firework singer – who are
both single since splitting from Kristen Stewart and John Mayer respectively –
puzzled onlookers when they were spotted checking out the wedding rehearsal of
two strangers at San Ysidro Ranch, not far from where Katy grew up.

Rehearsal guest Stephanie Sands told People.com: 'Katy
and Rob were just sitting next to each other watching the wedding rehearsal in
the main courtyard area. They were dressed very casually.

'She was wearing a
hoodie and big sunglasses. There was no PDA [public display of affection]
between them and no body language that showed they were dating.

'They just sat
together and watched.

'They were not affiliated with the wedding party and
were not seen mingling with guests.'

The 27-year-old British actor dumped his former Twilight Saga co-star, 23- who had a brief fling with married director Rupert Sanders last summer - recently after more than four years together because his friends, including the Firework singer, reportedly told him that he deserves better.

A source told Life & Style magazine that Perry, 28, was never a fan of the reconciliation: 'Katy never really supported Rob's decision to get back with

Kristen. She always said they wouldn't last.

'Katy told Rob she didn't think their relationship could withstand the cheating scandal. And he deserved better than someone who would destroy a family [like Rupert's].'

Despite the couple managing to patch
things up after a two-month break following Kristen's 'momentary
indiscretion' with Rupert last year, it is thought their relationship is
over for good this time after Rob was spotted moving his belongings out
of her home in Los Feliz last Sunday, where they both lived over the
last few months.

A large moving truck picked up the last of his belongings on Thursday.

A
source previously said: 'After everything that happened and the hurt
she caused, he's furious she'd be back in touch with him, even if she is
saying it's completely innocent.

'It does look like this it's over for good. He simply can't trust her.'

It was recently claimed Robert has never been happier
since splitting with Kristen.

A source said: 'Rob has never felt so free. He no longer has
to feel weighted by a girlfriend. Instead of being bummed that his relationship
hit a wall, Rob is simply glad to only have to be in charge of himself.'

'Through the years, Kristen definitely became too dependent on
him.

'Kristen keeps blowing up his phone but he’s not trying to
get dragged back into the past, so he’s not really picking up.'
